I am stuck trying to capture STDERR using &shell().
I am able to capture it using tcsh, but since &shell()
is sh-based, I need some sh-magic to get this working.
tcsh $ mpinfo -V |& cut -d' ' -f6-8

bash-3.00$ /opt/SUNWhpc/HPC6.0/bin/mpinfo -V 2>&1 cut -d' ' -f6-8
mpinfo: Sun HPC ClusterTools 6 10 Mar 2006 CRE 3.0
bash-3.00$ tcsh -c '/opt/SUNWhpc/HPC6.0/bin/mpinfo -V |& cut -d" " -f6-8'

No luck using "tcsh -c" with &shell().
